Do you have NDI tools installed on the vmix computer? If so, open the studio monitor and see if you can get the text in that.
If you're seeing the NDI feed from EW, it should show whatever you're sending from EW. Make sure the layers are stacked properly so the EW layer is on top.
I have a problem using Easyworship NDI when sending to my streaming computer.
I use Vmix to do live streams. I set up the easyworship computer to send text to the Vmix computer. When i open the available NDI options on the Vmix computer, I see the selection of Easyworship Live. I select it, but the text content from the Easyworship Computer is not showing. What am i doing wrong?
